A technique for ultrashort complex pulse generation based on the pulse shaping of superstructure fiber Bragg grating (SSFBG) is presented. We apply this technique to illuminate the mutual transformation between Gaussian pulse and soliton pulse, generations of double optical pulse and complex millimeter wave (MMW) pulse by phase and amplitude profiling of 1-ps transform-limited pulse. The designed principle of grating is demonstrated; the corresponding refractive index distribution, the reflection spectrum and the characteristics of pulse transmission are also simulated. The results of this study indicate that this design method is very flexible for complex pulse generations. Finally, some potential applications for these complex pulses in the areas of ultrafast photonics, optical measurement, novel devices for optical communication system and so on are also listed and discussed.
